I have not heard any recent updates on the momentary flashing purple line during 1080p playback over HDMI ( I still have this problem intermittently). I had read previously that at least one member solved their problem with a new HDMI cable. While playing around with the PJ this evening I observed something interesting:
With my PS3 directly connected to the projector via my HDMI cable ( Pannyoption menu displayed). The HDMI signal level, on the Panny, displays as "Normal" with the option to change it to "Expand". It stays in this mode while gaming. If I start playback of a DVD the "Normal" status blacks out and there is also no option to select this anymore. It would appear that the projector is not sensing the HDMI signal properly or the signal output level from the Sony has dropped causing this change. The movie still displays properly but I do get the intermittent purple line at times. The signal level always returns to "Normal" once I stop playback and go back to the main Sony options menu.
As an experiment, and since I just purchased an XBOX 360 Elite, I connected it directly via HDMI and performed the same test. Interestingly, the XBOX does not exhibit this same phenomenon. The HDMI signal level stays at "Normal" with the option to change it to "Expand" when playing games or during DVD playback at 1080p.
Maybe someone with access to a Panasonic engineer could ask about the HDMI signal level option and how that is being handled by the system. Could this be a software glitch? Why would it disappear for the PS3 and not for the XBOX? Is the Panny susceptible to a dropoff in HDMI signal input? Could this be contributing to the intermittent purple flash? Will Dorothy ever make it back to Kansas?
I have been tempted to try something like the Atlona HDMI signal booster but have been skeptical of its performance. The reason being is the current HDMI cable that I have is a very high quality one manufactured by Key Digital. The other option would be to purchase another high quality cable (of shorter length) and test to see if anything changes. I just have not had the time to do that.
I will post further experience if I decide to try a booster, go with a new cable or just banish the PS3 from the theater and give it a time out in game room
Updates to come,
